A New York man and woman who jumped to their deaths from the George Washington Bridge on Monday were homicide suspects, police say.

Nickie Hunt, 40, and Gary Crockett, 41, appear to have suffocated Hunt’s 70-year-old uncle William Valenti, who had accused them of stealing more than $1,000 from him, according to The Associated Press.

The AP reported that Hunt left a note addressed to "the four most amazing kids this world has ever seen or ever will." The note didn’t mention suicide or the killing, but Detective Craig Long said, "The tenor of the note indicates that she is going down a dark road."

Suffern Police Chief Clarke Osborn told the AP that while investigators are confident they have pieced together what happened, "We may never be able to answer some of the questions."
